Hello etraro,
I was also looking for some time the second part of the Me262 Classic series, since it isn't any more available at Amazon. I've found it here
http://www.sound-buecher-modellbau.c...roducts_id=663 at Rudi Penker's Bookshop.
A bit more expensive than Amazon, but I guess its worth it.
best regards,
Tomislav
